Family Maths Challenge

Each week I will include a maths problem for you to solve.

If you think you can solve it, with a bit of help from your family, email me the answer here with your name and class in the subject line, principal@skormond.catholic.edu.au

Each week at assembly I will announce the family who solved the problem correctly and the quickest. Good Luck!

In a class there are 20 students. They are wearing tops of 3 different colours – blue, green, and red.

The class was lined up in a way that the pattern of tops was: blue, blue, green, green, red, blue, blue, green, green, red... What colour jersey is the 20th wearing?

How many students are wearing a red jersey?
